'1 doll whom it may concem':

Be it knownthat I,' FRANK C. Rmscne, a. citizen of the United States,residing at Detroiqin' the county of Wayne, in 'the State of Michigan,have invented a certain new and useful Improvement in Adding-inachines'.of which the following is a specification.

The present invention relates to the papercarrying equipment of anadding and listing machine, and the principal object'is to provide animproved construction for automatically'returning a sheet of paper tothe starting point, in cases where several lists of figures are to beprinted in parallel vertical columns. The invention pertainsparticularly to the matter of control of the automatic paper returningmeans, and in this connection provides for efiec ting the return inconjunction with a tabulating or columnar shift of the paper carriage,this being accomplished (in the form of embodiment'of my invention hereillustrated) by depressing a key which first trips adetent for releasing a paper-returning spring, and then, when permitted to rise uponremoval of finger pressure, releases the paper carriage so that thelatter will be shifted by its spring to another columnar position.Provision is also made for automatically effecting the release of thepaper-returning spring when the paper has been advanced to a certainextent, e. 5 as determined by the complete rotation of a wheel in gearwith a roller platen. In addition to this. provision is made foroptional release of the paper-rcturning spring at any time withoutaccompanving or ensuing columnar shift of the carriage. and irrespectiveof the extent to which the paper may have been advanced. Furthermore,the paper-returning mechanism may at any time be disconnected from theplaten and the paper adjusted by hand through the turning of said platenunder control of a detent roll such as commonly employed to regulateline-spacing.

I have here shown the invention as applied to an adding and listingmachine of the well lcnown Burroughs 'type (see prior Patents 504.963and 505.078. issued September 12, 1893) though it is to be understoodthat the invention is not limited to employment in this particular t peof machine.

comprises perspective views of parts thereof.

Detailed description'of the adding and listing machine proper isunnecessary because of its being so thoroughly familiar to those skilledin the art through disclosures of the above-mentioned and numerous otherprior patents and through extensive marketing of the machine. It willsuffice, in this regard, to point out by reference to Fig.

' 1., that type plates 618 cooperate with a print amounts determined bymanipulation of keys 221; and that oscillation of the shaft 100 effectsstep-bystep line-spacing advance of said roller platen through familiarconnections such as illustrated in Patent No. 913,738 issued March 2,1909 and Patent No. 929,056 issued July 27, 1909.

The main frame of the paper carriage is designated by the numeral 17,the same being mounted as usual to slide upon a track-bracket l7 securedto the back plate of the machine. There is attached as usual to thisframe of the paper carriage a tape or band 18, which winds upon a springdrum l9 constantly tending to shift the carriage to the left. A rock rod20 is journaled in the lower part of said frame and carries a series ofadjustable tabulating fingers 21 which, through engagement with theshoulder of a stop plate 22 on the said back plate of the machine,determine the columnar positions of the carriage in a familiar manner. Ishall later on describe a special releasing arrangement for thetabulatin fingers 21, which arrangement provides for the carrying out;of one of the objects above stated, to wit, that of first releasing thepaper-returning spring and then releasing the paper carriage.

The roller platen 10 is mounted, as usual, in a cradle 12, pivoted uponthe carriage frame 17 so as to provide for swinging the platen into andout of printing position. in carrying out the present invention I pivotupon the left hand side plate of said cradle at the point 12 (Fig. 4) aplate 13, which constitutes the main support for the paper returningmechanism. There is screwed into the central portion of this plate a.stud 13 (Fig. 5), upon which stud there is journaled a sleeve 23, andupon this sleeve there is journaled a gear wheel 24 adapted to mesh witha pinion 10 secured upon the left hand trunnion of the roller platen. Ipreferably inte-rpose anti-friction balls 25 between the said gear Wheeland sleeve, the latter being grooved to accommodate said balls and asimilar groove being formed in the gear wheel by a beveled edge of theweb thereof and a similar edge of a plate 24, riveted to said web, asshown in Fig. 5.

There is formed integral with the web of said gear wheel a drum 24".within which is arranged a coiled spring 26 secured at roller platen 10to ,its outer end to the drum and at its inner end to the sleeve 23. Thelatter is formed at its inner end with a. ratchet flange 23 with whichcooperates an escapement palette 27 for regulating the tension of thespring in a familiar manner (dotted lines Fig. 4, see also Fig.- 8).

Obviously the spring, when under tension, tends to rotate the gear wheeland when the latter is in mesh the pinion 10, tends to reversely rotatethe platen. The arrows in Fig. 4 indicate the directions of rotation ofthese parts which the spring tends to effect, and of course thedirection of rotation of the platen is such as to run backward paperbetween it and the feed roller 11, which frictionally engages the platenin the usual manner.

Passing now to the matter of control of the aforesaid spring, there issecured upon the left-hand trunnion of the roller platen a V-toothedwheel 10, such as commonly employed upon roller platens for regulatingthe line-spacing under hand-turning, and a pawl or detent 27 (Fig. 4)normally engages said wheel to prevent backward turning of the platen bythe spring. This pawl or detent is in the nature of a lever pivotedintermediate its ends at 27 and held up as to its forward end by aspring 27 (see Figs. 4, 6 and 7).

Obviously, advance of the roller platen through the usual line-spacingmechanism will result in winding the spring 26, by reason of the platenpinion 10 turning the gear wheel 24 in a direction opposite thatindicated by the arrow adjacent said gear wheel in Fig. 4, and it willbe equally ob vious that return rotation of the platen and gear wheelwill be prevented by successive engagement of the pawl 27 with the teethof the wheel 10.

- Treating first of the release of the spring in connection with lateralshift of the paper carriage, a link 28 is pivotally hung from theforward arm of the detent lever 27 and slotted at its lower end toembrace a stud 29 secured in an arm 29, which is fastened to the rockrod 20 at the right hand end thereof, as the parts are seen in Fig. 2.The slot 28 is provided in the said link to permit disengagement of thedetent from the V-toothed wheel independently of the tabulating rock rod20 (as hereinafter de- 1'55 scribed). Obviously rocking of the rod 20 todisengage one of its fingers 21 from the stop plate 22 will result indisengaging the detent- 27 from the wheel 10 and thus releasingthe/spring 26 so that the platen branch 30 extending under the stopplate convenient place for mar'iipulation. A'spring explained s to therelease of the'pap'e passes and upin front of tlie same to present ahorizontal edge substan tiallfy flush with that st'o'p shoulder 22*(Fig; 3);

offset with respect tothe stop shoulder of theplat and adapted't'oengage' the finger 21and hold back the "carriage after the fing'er' hasbeen disengaged from" the shoulder 22'! Thus when the'lei er: is lifted,it

lifts the tabu'lating finger and disengagesit' from the stopshoulder2'2,' but the" anger then becomes engaged withthe stop"shoii'l'der 30", there being a very slight movement of the carriage takingtliefinger beyond the stop shoulder 22* so as'to prevent itsreeir'gagingthe same when the lever 30 drops. The latter is engagedby the rearend-of a lever 32, which is pivotedintermediate its" ends' on a framestud 32" (Fig. 1) andcou pled at its forward end'to a key 33, whiehprotrudes to the left of the keys 221 at a base of the machine anduph'olds said k and depresses the lever 30. Finger pressure" applied tothe key will obviously'lift the said lever '30 and'efi'eet the resultalready returning. spring and-disengagement of the tabulating finger from'the're'gular 'sto-p plate 22, but continued detention of'the carriage"by engagement of the finger with the shoul d'er 30". Upon' release of"the finger pressure the lever 30 drops and the carriage is released'and' propelled by the s ring-(111111119 and tape 18 to a new columnarposition which is determined by engagement of the 40'- nextfinger 21with the stop-plate 22.

The machine as thus f ar'deseiibe'd will be seen to greatly expeditetabulatingwork" by providing for ret-urnpf the'paper and shift to a newcolumn, as a result ofth'e mere touehing off'of a depressiblekey; the

paper being always returned to the same position so that the list-ingotieaclrqo lumn will begin along the sam'e'h'orizontal line.

Referring next to the matter of notifyingthe operator when the laStof'apredetei'Q mined number of operations has'been performed, there isscrewed into the endfof the stud 138a second" stud (Fig.f 5) upon whichis loosely mounted a sleeve 71 car rying a. bell 72. Thelatteris'perforated to embrace a screw-threaded reduced outer portion ofthe sleeve 71 and is clamped a ainst the shoulder of said sleeve'byathum nut 72". Th bell is engaged with a slot 71 in the said. sleeve soas to rotate therewith when the latter-is rotated throughengagement'with the gear wheel Sheltengzige ment is efli'ected throughtli'emediu'mof a radiiil arm 71 of 'tli'sleX-, bentoi ertoward" saidgearwh'eel and'fo'rliied'at its eiitiiiriiitfy to interlock with theteeth thereof. The sleere' is'slidable upon the stud 70 so thatbpulling'd it' upon the knob '72 the arm 71" may bedisengaged from thegearwheel and thenby' turning the knob any clesired setting canfb'hadto'predetermihe'tlie number of operations ofthe machine. To this endthe periphery ofthe" bell along the inner-edge thereof'is inscribed witha sca.le, as'clearly shown in'Fig. 11' (see also Fig. 2), and the plateJ 13 has an outward and downwardly turned'a rm 13 (Fig. 11:) wh'ieh isformed with an'indeX finger 13 adja cen'tsaid scale. A spiral springffitends'to engage the arn'i" 71 with the gear wheel, said springsurrounding'a reduced portion of the stud. 70' within a recess of th'eslee've'a'nd hearing at one end against a shoulder of the latter andat'th'e other against ahead on the outer end of the stud; all as'clcarlj' shown in F 5.

The index arm 13 above mentione h liesides being formed with the indexfinger or point-er" 13 is" formed adjacent thereto with a long finger13? beveled on both sides (Figs. 13 and 14 said finger extendinginwardly past the edge of the bell for the purpose of cooperating with abell-striking mechanism This mechanismcomprises a lever 77 (Fig'l 13')pivoted at 78 to the arm 71". and a trip lever 79 pit otedat 80 to thesaid lever 77.] said trip lever adapted to cooperate with thefiiiger ltll The lever 77 has'foi'med wi h itor' rigidly secured to it a resilient" stem SI'eXtehding in a 'curve on theinner side of the bell andcarrying at'it-s extremmy the bell-striker or clapper Asp'ring 83connects'an{armof'said lever T'T'W'ith a stud 84 upon the arm 71,tending to throw the bell-striker or clapper out-ward. An-

other spring 85 connects said stud with one Y strikes against the bossof the arm 71 where the lei'er 'f'l is pivoted and limits the action ofthe spring 85.

continued turning of the gear Wheel and arm 71 does'notresult in anyturning of the lever 79 upon its pivot but "does result in the turningof the lever 77 and the retraction of the'clapper or' striker 82 againstthe tensioni 1 of the spring 83;said lever 77 being-"slotted at 77 toenibra ee the stud St for the purpose of permitting a limited* 'swiiigixig.'

Theresultant concussion between the lower end of the slot 7 7 and the studSl causes the resilient clapper stem 81 to be thrown out with apercussive effect against the bell.

It is desirable to avoid a second sou nd ing. of the bell when the gear24 reverses carrying the arm 71 back witli'it. hat is the purpose of theparticular arrangement above described. Thus, the projection 79 havingbeen carried up in front of the finger 13, then upon backward movementofthe gear wheel, there will be a eamming action under this changedrelationship between these parts, which action rocks the lever 79 uponits pivot without again rocking the lever 77,- and therefore withoutagain striking the bell.

It is customary to setthcbell two steps in advance of the limit ofoperations to be performed so that, after the itemizing operation atwhich the bell sounds, there may be the usual blank or spacing operationfollowed by a totaling operation.

Taking up next the matter of automatic release ofthe paper-returningspring independently of the above-described tabulating devices and as aresult of the extent of advance of the roller platen, this in the pres'ent instance, results from the gear wheel 21 completing a rotation, andis chiefly advantageous to prevent over-winding of-the spring, though itcan be availed offer the purpose of effecting automatic release of thepaper-winding spring according to previous setting of the gear-wheel bythe bell-index. Said gear wheel has affixed to its web a lat eralprojecting lug 24? (Fig. 5) which is adapted, under rearward turning ofsaid wheel, to stop its movement and under forward rotation of saidwheel to trip the detent- 27. The normal condition is illustrated inFig. 4, said lug being engaged with a vertical shoulder 35 (dottedlines) of an arm 35 pivoted at 35 to the plate 13. A horizontal shoulder35 of said arm engages the upper side of said lug to limit the downwardmovement of the arm. The latter in rear of its vertical shoulder has acam edge 35 (dotted lines Fig. 4; full lines Fig. 6) adapted to be actedupon by the lug 24 (Fig. 6), when the gear wheel 24 completes arotation, whereby the arm 35 is lifted and the detent -27 disengagedfrom the wheel 10. The connection for effecting this is in the form of alink 36 slotted at its lower end to embrace a stud 27 carried by therear arm of the detent lever 27*, saidlink being pivotally coupledat itsupper end to the arm 35.

derstood of course, that the slot at the lower- I Since the latter islocated on the outer side of the plate 13 and the detent lever 2-7 endof the link is for thepurpose of permitting movemeiitof the detent leverindependently of the link 36, as in the case of disengaging said "detentfrom the wheel 10 by the tabulatingkey, as before described.

Inneither case should the detent 27 return to engagement with the platenwheel l0 untilthe paper has been run all the way back. Inuse'ofthetabulating key this can of course be taken care of by simplyholding down thekey until the paper has been completely run back, Inorder to insure this in'the case of the automatic tripping of the detentby the lug 24 when the said key is not used, the following constructionis employed: The arm 35 is extended in rear of its pivot and for 'nedwith a V-shaped eX- tremity 35, which cooperates with a'roller 37 uponan arm .37 pivoted to the plate 13 and drawn forward by a relativelystrong spring 38 ('Fig'. 6 Obviously the roller by engaging one side orthe other ofthe V- shaped extremity 35 will maintain the arm 35 in oneshifted position or the other, it being understood ofr c'ourse that thespring 38 is superior to the spring 2,7 which tends to return the detent27 to engagement with the wheel 10.

Through devicesn'ext to be described, the gear lug 24.is itself causedto restore the arm 35 to'a stopping position just ahead of thecompletion of 'the return rotation of the gear. "There'isp'ivotally'hungfrom a stud 39 at the upper end of the plate 13,. an arm 39 whichcooperates with said lug, said arm being connected by a springO toanother arm or link 41- mounted at its for ward end at the same stud 39and upon its rear end upon a stud 35 fastened in the rear extension ofthe arm 35. Normally, the spring e0 holds the arm 39in engagementwith-astop'stud. 41 on the arm 41, as shown in F igl 4:, the rearwardextension of the arm 35 being elevated and the roller 37" engagedwith-the under side of the V-shaped extremity 35'? thereof so that theforward end of the arm 35 is maintained in engagement with the lug 24.Normally,'the front edge of the arm 39 is flush with the shoulder 35*,asshown in Fig. 4, and so remains until, as the gear wheel 21 completes arotation accompanying advancemovement of the roller platen, its ,lug 24strikes a. rearwardlyi protruding nose 39 on the rear side of thearm 39and swings said arm forward stretching the spring .40, as illustrated inFig. 6. The lug then strikes the cam edge 35f and forces up the arm 35releasing the paper returning spring in'the' manner already described,and forcing the point of the V-sh aped end of said arm slightly overdead jceriter olf the roller 37. The arm 39 is swung 'rearward again byits spring 40 into contact with said stud 41 alongwith the tripping ofthe deten't 27 and resultant start backward of the gear 24: and its lug2 1?, the arms .41 and 35 being held, how- .ever, in displaced positionby reason ofjen- .gagement between the roller 37* and theV-shapedextremity 35 of the lever 35.. As the lug El approaches the endof its return rotation, it strikes the front edge of the arm 39 which,.owing to the lowered position of the rearward extension of the arm 35and the correspondingly lowered position of the rear end of the arm 41,is slightly in advance of the shoulder 35 of said ,arm 35 (Fig. 6), Thearm 39 isat the time engaged with the stud l1 so that the action of thelug against said .arm 39 effects upward movement of the arm 41 andconsequently of the rearward extension of the arm 35 and thereby theshoulder 35* of the latter is drawn down fully into the path of the lug24: which lands against it .so that the gear is stopped in its normalposition illustrated in Fig. 1. This action at the outset carries theV-point 35 upwardly across dead center {of the roller 37 so that thespring 38 then aids in lowering the shoulder 35 into full stoppingposition.

It remains to describe the release of the paper-returning spring by handat the will of the operator whenever he desires to run the paper backwithout the use of the tabulating key and without waiting for the gear24 to complete a rotation; also the means whereby the platen may bedisconnected from the spring and unlocked so as to permit ordinarymanipulation backward or for ward to adjust the paper, or to permitemployment of the machine without the paperrcturn feature.

The first of these things (Fig. 7) is accomplished by the simpleexpedient of pivoting upon the plate 13 at the point 43* a hand lever 43having an upwardly extending branch, given a right angle twist toprovide a handle 43, and having afor wardly extending branch 43overlying the ,detent 27. This hand lever is normally upheld by a spring4st connecting it with a stud 13 on the plate 13, said stud also servingto limit backward swing of this hand lever. Obviously, a forward pullupon the handle of this lever will result in displacing the detent, asillustrated in Fig. 9, whereupon the platen will be run backward untilthe lug 24 of the gear 24 lands against the stop shoulder 35.

As to disconnecting the platen for paper adjustment or ordinary use ofthe machine,

it has already been stated that the return mechanism is carried by aplate 13, which is pivoted to the cradle 12 This provides for engagingand disengaging the gear 24 and pinion 10*. A relatlvely strong spring45 connects the said plate 13 and the rear portion of the cradle in suchmanner as to swing the plate rearwardly and disengage the gear wheel .24from thepinion. (The upper end of said spring being attached to the sameplate-stud 1.3 as the spring 4 1.) For the purpose of holding the plateforward in opposition tothis spring and maintaining the engagementbetween the gear wheel and thepinion, I pivot upon the plate- 13 at 46*(Fig. 7) a .latch -16 which is adapted to engage over a stud .12 on thecradle, the engagement being enforced by a spring 46* which connects thelatch with the same stud 13 of the plate 13 :to which the upper end ofthe spring 4H is attached. A handle 47 pivoted on the same stud whichsupports said latch projects conveniently for manipulation :and has astud 47 to operate upon an upward extension 46 of the latch. The latter.through a beveled formation at its forward end is designed toautomatically engage over the stud 12 when the plate 13 is forcedforward. Obviously rearward movement of the handle 47 will disengage thelatch from said stud and cause the plate to swing rearwardly (Fig. 10).

.Discngagement of the detent 27 from the platen wheel 10 as an incidentto the rearward swinging of the plate is accomplished as follows: Thehub 13 of the plate 13 is interlocked with the hub .8* of an arm 48(Fig. 11) which has a Stud 48 occupying a shortslot 27 in the detent 27.VYhen the latter is engaged with the V-t-oothed wheel 10, as illustratedin Fig. t, the said stud 18 is at the lower end of said slot (dottedlines in said figure). Therefore, when the plate 13 is swung rearwardunder these conditions, the accompanying downward stroke of the arm 18will result in disengagement of the detent 27 from the wheel 10 (Fig.10). I also provide in this same action for establishing the usualline-spacing control through engagement of a roll 50 with the V-toothedwheel 10. This roll in the present instance is mounted on the end of anarm 51 pivoted in the cradle and drawn forward by a spring 52 butnormally held away from the wheel 10 by the arm t8, the latter beingformed with a nose 48 which engages a forward branch 51 of said arm 51.Obviously when the arm 48 is swungdown as above described, the arm 51 isreleased and the spring 52 will then engage the roller 50 with thetoothed Wheel 10 so as to establish the usual line-spacing regulationwhile permitting the turning backward or forward of the platen by theknob 10 on the right hand trunnion thereof (Fig. 2). This customaryengagement between the platen wheel and regulating roller would beundesirable when the automatic paper control is in commission because ofits interference with the easy running backward of the platen by thespring. Tt is unnecessary as a line-space regulator then because thedetent 27 serves the same purside.

pose. Obviously the equipment last above described provides forrecording without the automatic paper-return attachment. The swingingback of the plate 13 does not disturb the line-spacing connections fromthe shaft 100. It is limited by a stud 13 engaging a slot 12* in theside plate of the cradle.

I preferably regulate the speed of the paper-return so that it cannotbecome excessire, by a centrifugal governor. This is in the form of adrum secured against the inner side of the plate 13 (Fig. 2) andiiiclosing a set of segmental shoes 61 (Fig. 7) which occupy substantialquadrants of the drum and are loosely arranged between radial pins orspokes 62. The latter are carried by a hub 63 secured to a shaft 64which is journaled in the drum and in the plate 13, and on the outerside of the latter carries a pinion 65 (Fig. 1) in mesh with the gearwheel 24. Excessive speed of the latt-cr throws the shoes 61 outwardlyagainst the inner wall of the fixed drum so that the gear isfl'ictionally retarded.

Passing now to the matter of supportin a sheet of paper so that it maybe readil fed into the machine, and as readily run ack, and referringmore especially to Figs. 1720, there is rigidly mounted upon the cradle12 a sheet metal plate extending the full length of the platen and acqnsiderable dis tan'ce upward, said plate'be'ing inclined rearwardly soas to support a sheet of paper in such manner that it will not likelyfall forward 'over the machine. The said plate is flanged at the endsand its upper rear por-- tions connected by stay bars or braces 91 withforwardly projecting arms of the side pieces of the cradle. The plate isfurther stiffened by an angle piece 92 which extends from side to sideand is riveted against the back of the plate, as shown in Fig. 18. Theplate is slotted crosswise on both sides of the central portion, asshown in Fig. 17, to provide for lateral adjustment of angular guidelates 94L which lie against its front he outstanding flanges of theseguide plates serve as guides for the side edges of the sheet of paperand it is of course important that they shall always stand at rightangles'to the platen. For the pur pose of insuring this and at the sametime varying the adjustments of said guide plates I secure against therear sides of the latter, elongated metal blocks 95, which arerectangular in cross-section and occupy the horizontal slots 90 in theback plate 90, the latter being flanged along the upper edges of saidslots, as shown in Figs. 1, 7 and 10. I form with or rigidly'attach tothe blocks 95' screw-threaded stems 95 (Fig. 20) to which ar'e'appliedthumb nuts 96 for the purpose of clamping the guide plates to the backplate. In orderto do this most effectively I employ speciallyconstructed clamping pieces or clips 97 perforated to engage looselypverthe screw-threaded stem 95 between the blocks 95 and the bases of thescrew nuts 96, and formed to engage closely over the flanges of the backplate 90 which extend along the upper sides of the slots 90, besideswhich said clips are also given a right-angled formation for closeengagement with the under sides of the blocks 95. They also havesomewhat extended flat portions to bear against the rear side of theback plate. It will be obvious that the above described arrangementprovides for very securely clamping the guide plates in position andinsuring the preservation of the proper right-angle relation betweentheir outstanding flanges and the platen, while at the same timeproviding for an easy adjustment of the guide plates through the use ofthe thumb piece 96,all without recourse to upper and lower guide slots.

In order to provide for supporting the upper part of an extra long sheetI arrange an extension piece 98 at the center of the plate 90, as shownin Figs. 17 and 19. Said plate 90 at its middle is given a trough-likeformation, as shown at 90, and said extension piece is similarly shapedto slide therein, being slotted longitudinally to provide for a widerange of adjustment. A screw 90" in the upper portion of the trough ofthe plate 90 extends through said slot and its head engagesover afriction piece 99 which overlies the edges of the slot so that thetightening of nut 90 on said screw will hold the extension piece 98 inthe position to which it is brought. The adjustment of said extensionpiece is facilitated by form ing a finger piece 98 at its upper end.

Of course it is not essential to the carrying out of my invention that aplaten be employed for it is not so much the function-v ing of theroller as a platen that counts as its functioning for paper-feedpurposes. Therefore, in claims which follow the term feed roller isemployed, so as not to restrict .to a feed roller which is also aplaten.

I claim:
